# Welcome to 🤏 Pin Model Series
The models in the LH-Tech AI Pin Series are very small models that were trained on starhopp3r/TinyChat.

## Models overview
| Model | Parameters | Training iters | Final Train Loss | Quality | Example Chat |
|:----|:----|:----|:----|:----|:----|
| Pin-5M  | 5.37M  | 1000 | 3.170788 | Very Poor | Yes, a bright day is shining and makes everything have a good day a lot. |
| Pin-10M | 10.06M | 1500 | 2.562048 | Very Poor | That sounds nice, I agree, it is nice to talk about new ideas. |
| Pin-15M | 14.84M | 1500 | 2.358367 | Low | It is hard to see your plans when you want to enjoy the day. |
| Pin-20M | 21.03M | 1500 | 2.217588 | Medium | Yes, sunny days are wonderful! I love hearing about the sunshine and the sun's shining on. |
| Pin-25M | 26.76M | 1500 | 2.139837 | Medium | Sunny days make everything look brighter, especially with a nice friend who cares. |
| Pin-Ultra-25M | 26.76M | 8000 | ... | ... | Coming soon... |

\* All models were prompted with `What is the weather like today?`.

🚀 **We recommend using Pin-Ultra-25M.**

## Training
### Training data
We trained on [starhopp3r/TinyChat](https://huggingface.co/datasets/starhopp3r/TinyChat) and used the gpt-2 tokenizer.

### Training code/scripts
You can find the full training code for the Pin Model Series in this repo.<br>
**Tip:** If you want to train one of these models yourself, make sure to adjust the model config like this:
| Model | n\_layer | n\_head | n\_embd | n\_inner |
| :---- | :---- | :---- | :---- | :---- |
| **Pin-5M** | 4 | 8 | 96 | 384 |
| **Pin-10M** | 6 | 8 | 160 | 640 |
| **Pin-15M** | *8* | *8* | *208* | *832* |
| **Pin-20M** | *10* | *8* | *256* | *1024* |
| **Pin-25M** | *12* | *12* | *288* | *1152* |
| **Pin-Ultra-25M** | *12* | *12* | *288* | *1152* |

Have fun :D

### Training details
We trained all these models in ~30 minutes on a single T4 GPU in a Kaggle Session.<br>
So you are able to easily recreate all of the Pin model without having to launch a 8xH100 cluster 😂

## How to use the model
You can easily use the favorite model of the Pin series like this:

1. Download `use.py` from this repo.
2. Adjust the subfolder argument here:
   ```python
   answer = run_pin_inference(user_query, model_id="LH-Tech-AI/Pin", subfolder="Pin-25M") # use your favorite model here, e.g. "Pin-25M" or "Pin-15M"...
   ```
3. Adjust the input prompt here:
   ```python
   user_query = "What is the weather like today?" # insert your prompt here
   ```
4. Launch it with Torch installed in Python3.
5. Have fun :D
